To all whom it may concern.'

:Be it known that I, JOHN W. Cox, a subject of the King of GreatBritain, having declared my intention of becoming a citizen of theUnited States, residing at Erie, in

the county of Erie andState of Pennsyl- 1 This 'invention relates topacking machines and Consists in certain improvements 'Miri theconstruction thereof as will be hereinafter fully described and pointedout in the Vclaims. v

More particularly the invention relates to a machine which is designedto load or ack receptacles where it is' necessary to jar own the'material. This is particularly true in loading the annealing pots ofmalleable cast- 'ings wherein the castings are mixed with anmateriaL'ordinarily such as oxid annealin j iron.V Hgere it is necessaryto shake down the anrgiealing material so that it will lill theinterstices between the castings. These annealing pots are ordinarilymade in sections so that itis desirable to have the top of each IconvenientlyT loaded withcastings from the l' tlush'with the floor.

The sections arevmounted on aplatform or carrier 2 and this platform is adapted to beadjusted with relation to the floor 3 from which Vthe re ceptacles areloaded.

to exhaust the water from the cylinder by way of the pipe 8". In thisway the platform 2 may be nicely adjusted so as to bring 'the top ofthesection which is being loaded at or about flush. with the {ioor Sand theplatform can be maintained in this positionL by simply closing the valve8a and locking the fluid in the cylinder. Chains 9 are. provided withthe platform and the cylinder to prevent the forcing of the plunger outof the cylinder.

The cylinder 5 has an extension 10 which forms a plunger operating in acylinder 11. The cylinder .11 is mounted on a base. 12.

Projections 13 extend from .the cylinder and bolts 14 extend from theseprojections through perforations 15 on the cylinder 11. Nuts 17 arearranged. on the bolts or studs i 14 and these coming intocontact withthe `projections 16 limit the upward movement of: the plunger 10v andconsequently the. up-

ward. movement of the cylinder 5. It will bey noted that when this ismoved upwardly through the action of the plunger 10, the lungermaintains its relation to the cyliner ,5. l

The purpose of the plunger 10 operating as itdoes in the cylinder 11 isto form a shaker by means of which the material may be more thoroughlypacked in the receptacles. To accomplish this, the plunger 10 iselevated and then the liquid under it is freely released, allowing it topractically drop so as to supply sullicientshock to the material in thereceptacle to assure its filling in the interstices in the castings.

The cylinder 11 is supplied through a pipe 18. This pipe 18 is Connectedwith the main pipe 19. The pipe19 has a T `20 from The valve `whichalternates ythe How of liquid to and from the pipe 18 is as follows: Thevalve chamber 23l is provided withthe which branch pipes 21 and 22extend to the 4valve chamber 23. f

A valve stem 30 connects ythe .yal-ves 2 8 and 29 and formsarmeans of eonnetion for actuating the valves. 5A supply pipe 31 leadstothe v'alvehamloer opposite the port 26. An exhaust pipe 32.leads fromthe port 27 and the pipe 21 leads from therfvalve.ohamhersopposite theport127. In-
